Important Information

Through  our  ongoing  efforts to reduce  expenses  and  respond to  shareholder
requests, your annual and semiannual report mailings are "streamlined." One copy
of each report is sent to each  address,  rather  than to  every  registered  
owner.  For  many shareholders and their families,  this eliminates duplicate 
copies, saving paper and postage costs to the Fund.

If you are the  primary  shareholder  on at least  one  account,  prefer  not to
participate in streamlining, and would like to continue receiving one report per
registered account owner, you may request this in writing to:

MESSAGE FROM THE PRESIDENT


   In the last few years I have  turned my  attention more and more to the
   subject  of  tax-efficient  investing.   Though a  few fund  companies 
   are beginning to write  about this  subject,  it remains off the beaten
   track of mutual fund investing. But I believe it is of great importance.


[PHOTOGRAPH OF PRESIDENT: MICHAEL J.C. ROTH, CFA APPEARS HERE]


Just  recently a close friend whom I have advised for years asked me, "Will my
tax bracket be lower when I retire?" I told him, "No. I will not permit that." I
believe  that  much  financial  planning  makes  an  invalid  assumption  that a
retiree's tax bracket will fall  substantially  when retirement comes. But it is
quite  possible  for a person  whose income is in a high tax bracket to build an
estate  that  will  sustain  that  bracket  upon  retirement.  If  that  occurs,
tax-efficient investing can be very important.

For a mutual fund investor that means maximizing potential tax-exempt income and
long-term  capital  gains.  Unfortunately  all of the  distributions  from IRAs,
401(k)s,  and  variable  annuities  will be  taxed  as  ordinary  income.  But a
non-sheltered  portfolio of index funds or efficiently run equity portfolios can
be harvested  principally  as long-term  capital gains at a 20% tax rate. And an
accompanying  investment in tax-exempt funds may provide the fixed-income buffer
to stock  market  risk  along  with the  potential  for  significant  tax-exempt
returns.  Such a  non-sheltered  portfolio  may  be a  valuable  addition  to an
individual's  investment plan and may provide valuable assistance while you live
through your retirement.

Much of the  attention of financial  planners is  concentrated  on preparing for
retirement.  You must not overlook the fact that you have a good  possibility of
enjoying decades of reward for your good planning after you retire.

Sincerely,


Michael J.C. Roth, CFA
President and
Vice Chairman of the Board

Data Since Inception on 8/1/94 through 3/31/98




The broad-based Lehman Brothers Municipal Bond Index is an unmanaged index that 
tracks total return  performance for the long-term investment grade tax-exempt 
bond market.  The Lipper Texas Municipal Debt Funds Average is the average  
performance level of all Texas Municipal Debt Funds, as computed by Lipper 
Analytical  Services, an independent organization that monitors the performance 
of mutual funds.  All tax-exempt bond funds will find it difficult to 
outperform  the Lehman Index, since funds have expenses.
                             




                  Message from the Manager


[Photo of Portfolio Manager, Robert R. Pariseau, CFA, appears here.]


THE ECONOMY 

The U.S. economy continues its 8th year of expansion with remarkably few signs
of inflation.  The yield on the 30-year U.S.  Treasury Bond (the "Long Bond") 
fell to a decade low of 5.69% on January  12,  1998.  Nevertheless,  bond
investors  now  seem  less   confident   that  the  weakness  in  Asia,   higher
productivity, El Nino, a relatively tight monetary policy and other factors will
suppress inflationary pressures. Concerns over the robust U.S. economy have been
a  recurrent  theme for many  months now.  Currently,  investors  seem to lack a
consensus  regarding the  direction of the next interest rate  adjustment by the
Federal  Open  Market  Committee  (FOMC,  or "the  Fed").  Personally,  I'm more
confident  that economic  conditions are more akin to the stable prices and real
growth experienced in the 1950s than the high inflation of the 1970s.

YOUR DIVIDEND YIELD
As interest  rates have fallen, our sales force has received  inquiries from
investors asking whether high coupon(1) bonds will be called away from various
USAA tax-exempt funds.  These  investors  are  obviously  concerned  that their
fund's  yield will drop dramatically.  The majority of municipal bonds permit 
issuers to "call," or redeem, a bond many years before the stated maturity.  
Typically,  municipal bonds may not be called until  after ten years from the
date of  issue.  An  issuer  would  call,  or refinance, a bond for the same 
primary reason that a homeowner would refinance a mortgage -- when interest 
rates drop  sufficiently  to more than offset the cost of refinancing.

Let me assure  you that I am very  conscious  of call  features.  I  continually
evaluate the relative market value of various bond coupons and their  respective
call dates. For high coupon bonds, I typically hold them as long as possible. If
I sold a higher coupon bond at a large  premium (i.e.  market value exceeds face
value),  the Fund  would  lose the  tax-exempt  income  stream  prematurely.  In
addition,  the  transaction  may  trigger  a  federal  capital  gain tax for our
investors. I consciously manage the Fund to minimize capital gain distributions.
When high coupon bonds are eventually called, typically the impact on the Fund's
distribution  yield is quite  muted,  maybe a few basis points (a basis point is
 .01%) for even a very large position of the Fund's highest yielding bond.


(1) A bond's coupon is the fixed amount of interest that is paid annually stated
    as a percentage of face value, normally $1000.  For example, a 6.5% coupon 
    pays $65 (6.5% times $1000 = $65) normally in two semiannual payments of 
    $32.50 for the life of the bond.



PORTFOLIO STRATEGY
I focus  primarily on  generating  maximum  tax-exempt  income that  potentially
should  produce  the best  after-tax  total  return  over a 3-5 year  investment
horizon.  I do not buy exotic  derivatives,  nor do I hedge the  portfolio  with
futures  contracts.  I have no intention of purchasing  municipal bonds that are
subject to the federal alternative  minimum tax (AMT) for individuals.  In fact,
since  inception,  the USAA Texas  Tax-Free  Income  Fund has never  distributed
income  that was  subject to the AMT. Of course,  I would  certainly  advise our
shareholders  if there were a change in the Federal Tax Code that  compels me to
reconsider  my  position  on the  AMT.  I remain  cautious  about  investing  in
municipal lease obligations.


THE MUNICIPAL MARKET
Interest  rates have  fallen  almost the entire  fiscal  year.  The yield on the
30-year U.S.  Treasury Bond (the "Long Bond") began the fiscal year at 7.10% and
ended the period at 5.93%. The tone of the  municipal  bond  market is  similar
to what I  described  last September in the Semiannual  Report.  In general, 
the municipal market does not reward an investor for buying bonds much beyond 20
years in  maturity, although on occasion I have found some interesting values.  
And  similar to last fall,  I have been buying fewer BBB and A-rated  bonds  
compared to the past,  because of their low yields relative to higher rated 
bonds.

YOUR FUND'S PERFORMANCE: #1 IN THE HEART OF TEXAS
I'm very pleased to say that Morningstar recently awarded the Fund "Five Stars"
for the overall and 3-year  ratings as of March 31, 1998,  overall and among
1,525 funds, in the municipal bond fund category.(2) In addition, the Fund 
earned Lipper Analytical Services' Inc.  Performance Achievement Certificate 
for ranking #1 out of 20 in Lipper's Texas Municipal Debt Fund category for 
the 1-year period ended  12/31/97.(3)  Average annual total returns for the 
1-year  period  ended 12/31/97 and the 8/1/94 to 12/31/97 period were 11.71% 
and 10.09%, respectively.  The Fund has ranked #1 in that category for three  
consecutive  calendar years - 1995, 1996, and 1997.

Past performance is no guarantee of future results.

(2) Morningstar proprietary ratings reflect historical risk-adjusted performance
through March 31, 1998. The ratings are subject to change  monthly.  Morningstar
ratings are calculated  from the Fund's 3-,5-,  and 10-year average annual total
returns,  as  applicable,  in  excess  of  90-day  Treasury  bill  returns  with
appropriate fee  adjustments,  and a risk factor that reflects fund  performance
below  90-day  Treasury  bill  returns.  There is a 3-year  minimum  performance
requirement  before a fund is rated.  Overall rating is a weighted  average of a
fund's 3-,5-,  and 10-year  ratings,  as applicable.  The top ten percent of the
funds in a rating category  receive five stars,  and the next 22.5% receive four
stars.

COMPARISON - 12 MONTH DIVIDEND YIELD
- ---------------------------------------

A chart in the form of a bar graph appears here illustrating the comparison of
the 12 month Dividend Yield of the USAA Texas Tax-Free Income Fund and
the Lipper Texas Municipal Debt Funds Average from 3/31/96 through 3/31/98.


               USAA Texas Tax-Free                   Lipper Texas Municipal
                Income Fund Yield                       Debt Funds Average*

3/31/96               5.52%                                   5.02%
3/31/97               5.58%                                   4.98%
3/31/98               5.15%                                   4.68%





12-month dividend yield is computed by dividing income dividends paid during the
previous 12 months by the latest  month-end net asset value adjusted for capital
gains distributions.  The graph represents data from 3/31/96 to 3/31/98. 



While past performance is no guarantee of future results, the Fund ranked #1 by
Lipper among Texas Municipal Debt Funds for the past 12 months, ending March 31,
1998, with a total return(4) of 13.71% as compared to the average of 10.35% for 
the 20 funds in the category.  For the same period and category,  the Fund's 
dividend  distribution yield(5) was 5.15% as compared to the Lipper  Average 
of 4.68%.  Your  Fund's net asset value per share  increased  by $.72, or 
6.9%, since March 31, 1997, adjusting for the $.0479 and $.0471 capital
gains distributed on May 14, 1997, and December 30, 1997, respectively.




* Refer to Page 4 for the Lipper Average Definition.

(4) Total return equals income return plus share  price change and  assumes
reinvestment  of all  dividends  and  capital  gain  distributions.  

(5) 12-month dividend yield is computed by dividing income dividends paid during
the previous 12 months by the latest  month-end  net asset value  adjusted for 
capital  gains distributions.



THE STATE OF TEXAS
A warm weather  environment,  favorable tax rates,  and a young labor force have
made the state attractive for relocating  businesses.  During this decade, Texas
has added more jobs than any other  state.  The  state's  close ties to Mexico's
markets  enhance  international  trade.  Texas  remains the second most populous
state,  behind only California,  having grown nearly twice as fast as the nation
at large since 1990. Reflecting strong credit fundamentals,  Texas maintain high
bond  ratings of Aa2,  AA+, and AA from Moody's  Investors  Service,  Standard &
Poor's, and Fitch IBCA, respectively.

The Texas economy has diversified away from the resource based economy of the 
1980s to a structure similar to the rest of the U.S. For example, in the first 
half of the 1990s,  Texas gained more high tech jobs than any other state.  
Texas is now second only to California in total high technology employment.  
Making good on a promise,  the  legislature  has passed a $200  million program 
to fund a school construction  program  that  favors the  poorest  districts.  
In  addition,  the legislature is studying  possible  solutions for the growing 
water shortages in some regions. We will closely monitor these and other issues 
that might impact your Fund's holdings.

Total return equals income return and assumes  reinvestment of all dividends and
any capital gain distributions. No adjustment has been made for taxes payable by
shareholders on their reinvested dividends and capital gain distributions.  Past
performance is no guarantee of future results. Yields and returns fluctuate. The
7-day yield quotation more closely  reflects  current  earnings of the Fund than
the total  return  quotation.

Message from the Manager

THE MARKET
How long can the economy  continue to expand?  How long can  inflation  stay low
despite  rising  wages and  falling  unemployment?  To what  extent  will  Asian
economic problems affect our economy? Who knows!

It certainly would be nice to have the foresight to answer the above  questions,
but even with the  correct  answers,  one would not know  whether to lock in one
year rates or invest in shorter term  securities.  As mentioned in the last 
semiannual  report,  the short-term   municipal   market  is  primarily  driven
by  supply  and  demand relationships.

The Federal  Reserve  (Fed)  increased  the  federal  funds rate (the rate banks
charge one another for overnight  loans) .25% in March 1997. The Fed has been on
hold since  then.  For the last twelve  months,  one year  treasury  bill yields
generally  declined  within a range of 6.07% to 5.08%,  and ended  March 1998 at
5.39%. During the same period, yields on municipal notes as measured by the Bond
Buyer's One-Year Note Index,(1) ranged from 3.97% to 3.51%, and ended March 1998
at 3.64%. Supply and demand factors caused a spike up in yield at the end of the
calendar  year.  Yields  were low during the first  three  months of 1998 as the
market  experienced  large cash inflows (which increased demand) during a period
of little new supply.  How long will this continue?  Again, no one really knows.
However  certain   seasonal   factors  and  corporate  buying  habits  are  more
predictable and should produce buying opportunities to lock in higher yields.

(1)  Bond Buyer Index is the industry standard for yields of investment grade
municipal bonds.

STRATEGY
Your Fund strives to meet its objective in any  prevailing  market  environment.
Rather than trying to predict future interest rates, we focus on buying the best
relative value in the market at any given time.  This reflects our longstanding
commitment  to credit  research,  and a judgment as to whether  the Fund would
be  sufficiently compensated with additional  yield to invest in longer term 
securities.  Because of the lack of supply during the first three months of 1998
(and low yields on what was available), your Fund's average maturity is 
relatively  short. This will provide the liquidity  necessary to take advantage 
of higher yields during the coming months as opportunities arise.

PERFORMANCE
While past performance is no guarantee of future results, for the 12 months 
ending March 31, 1998,  your Fund ranked 5 out of 156 State Specific Tax-Exempt
Money Market Funds according to IBC Financial Data,  Inc.(2) with a compounded  
dividend yield of 3.43%. The average for the category over the same period was
3.04%.

TEXAS
The Texas economy  continues to perform  well,  adding jobs and  increasing  the
Gross State Product (GSP) at a steady pace.  Employment  growth of 2.73% in 1997
continues to outpace the national  average of 2.20%, but at slower rates than in
previous  years.  Output as measured by GSP increased 4.2% in 1997. The benefits
of  economic   diversification   are  evident  as  Texas  moved  away  from  the
resource-based  economy of the 1980s to an economy with similar  characteristics
to the rest of the U.S. Unlike the 1980s, the Texas economy is still very strong
despite the  significant  decline in oil prices over the last twelve  months.  A
moderate  climate,  favorable  tax rates,  close  proximity  to  Mexico,  and an
abundant labor force combine to make Texas attractive for businesses.

The state budget,  with its reliance on the cyclically  sensitive sales tax, has
benefited from consistent  economic growth.  For the fiscal year ending 8/31/97,
the state ended with a $2.7 billion positive cash balance in the General Revenue
Fund (the state's main operating fund).  Given the positive economic outlook for
Texas and prudent  fiscal  management,  we would  expect the state to maintain a
strong financial  position.  We continue to analyze each issue on a case by case
basis and remain very selective when investing fund assets.

Independent Auditors' Report
The Shareholders and Board of Trustees

USAA STATE TAX-FREE TRUST:
We have audited the accompanying statements of assets and liabilities, including
the portfolios of investments in securities,  of the USAA Texas Tax-Free  Income
and USAA  Texas  Tax-Free  Money  Market  Funds,  portfolios  of the USAA  State
Tax-Free Trust as of March 31,  1998,  and the related  statements of operations
for the year then ended,  the  statements  of  changes in net assets for each of
the years in the two-year period then ended, and financial  highlights presented
in note 7 to the financial  statements  for each of the years or periods in the 
four-year  period then  ended.  These  financial  statements and financial  
highlights  are the responsibility of the Company's management.  Our 
responsibility is to express an opinion on these financial statements and 
financial highlights based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements and financial  highlights.  Our procedures  included  confirmation of
securities owned as of March 31, 1998, by correspondence  with the custodian and
brokers.  An audit also includes  assessing the accounting  principles  used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion,  the financial  statements and financial  highlights referred to
above present fairly, in all material  respects,  the financial  position of the
USAA  Texas  Tax-Free  Income  and  USAA  Texas  Tax-Free  Money  Market  Funds,
portfolios of the USAA State Tax-Free Trust as of March 31, 1998, the results of
their  operations  for the year then ended,  the changes in their net assets for
each  of the  years  in the  two-year  period  then  ended,  and  the  financial
highlights for each of the years or periods in the four-year  period then ended,
in conformity with generally accepted accounting principles.

CATEGORIES & DEFINITIONS
PORTFOLIOS OF INVESTMENTS IN SECURITIES

March 31, 1998

Fixed-Rate  Instruments  - consist of municipal  bonds,  notes,  and  commercial
paper. The interest rate is constant to maturity.  Prior to maturity,  the price
of a  fixed-rate  instrument  generally  varies  inversely  to the  movement  of
interest rates.

Variable  Rate Demand Notes (VRDN) - provide the right,  on any business day, to
sell the  security  at face  value on  either  that  day or in seven  days.  The
interest rate is adjusted at a stipulated daily,  weekly, or monthly interval to
a rate that reflects  current  market  conditions.  In money market  funds,  the
effective  maturity is the date on which the underlying  principal amount may be
recovered  or  the  next  rate   adjustment   date  consistent  with  regulatory
requirements.  In bond funds, the effective  maturity is the next put date. Most
VRDNs possess a credit enhancement.

Credit  Enhancement  (CRE) - adds the financial  strength of the provider of the
enhancement to support the issuer's ability to repay the principal when due. The
enhancement may be provided by either a high quality bank, insurance company, or
other  corporation,  or a  collateral  trust.  Typically,  the  rating  agencies
evaluate  the  security  based upon the credit  standing of the  provider of the
credit  enhancement,  rather  than the credit  standing  of the  issuer.  If the
securities  are enhanced by a bond  insurer,  scheduled  principal  and interest
payments are insured by:

         (1)      Municipal Bond Insurance Association.
         (2)      AMBAC Indemnity Corp.
         (3)      Financial Guaranty Insurance Co.
         (4)      Financial Security Assurance, Inc.
         (5)      American Capital Access.
         (6)      Texas Permanent School Fund.

The insurance does not guarantee the market value of the municipal bonds.

NOTES TO FINANCIAL STATEMENTS

March 31, 1998

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
USAA State Tax-Free Trust (the Trust), registered under the Investment Company
Act of 1940, as amended, is a diversified,  open-end  management  investment
company  organized as a Delaware business trust  consisting  of four  separate
funds. The information presented in this annual report pertains only to the USAA
Texas  Tax-Free  Income  Fund and USAA Texas  Tax-Free  Money Market Fund (the
Funds).  The Funds have a common  objective of providing Texas investors with a
high level of current interest income that is exempt from federal income taxes.
The USAA Texas Tax-Free Money Market Fund has a further objective of preserving
capital and maintaining liquidity.

A. Security  valuation - Investments in the USAA Texas Tax-Free Income Fund are
valued each  business  day by a pricing  service (the  Service) approved by the
Trust's  Board of Trustees.  The Service  uses the mean  between quoted bid and
asked prices or the last sale price to price  securities when, in the Service's
judgement,  these prices are readily  available  and are representative  of the
securities'  market  values.  For many  securities, such prices are not readily
available. The Service generally prices these securities based on methods which
include consideration of yields or prices of municipal securities of comparable
quality,  coupon,  maturity and type, indications as to values from dealers in
securities, and general market conditions.  Securities which are not valued by
the Service, and all other assets, are valued in good faith at fair value using
methods determined by the Manager under the general supervision of the Board of
Trustees. Securities purchased with maturities of 60 days or less and, pursuant
to Rule 2a-7 of the Investment Company Act of 1940, as amended, all securities
in the USAA Texas Tax-Free Money Market Fund, are stated at amortized cost 
which approximates market value.

B. Federal taxes - Each Fund's policy is to comply with the  requirements of the
Internal Revenue Code applicable  to  regulated  investment  companies  and to
distribute  substantially all of its income to its shareholders. Therefore, no
federal income or excise tax provision is required.

C. Investments in securities - Security transactions are accounted for on the 
date the  securities  are purchased or sold (trade date).  Gain or loss from 
sales of investment  securities is computed on the identified cost basis. 
Interest income is recorded  daily on the accrual basis.  Premiums and original 
issue  discounts are amortized over the life of the respective  securities.  
Market discounts are not amortized.  Any ordinary  income  related to market  
discounts is recognized upon  disposition  of  the securities.  The Funds  
concentrate their investments in Texas municipal securities and therefore 
may be exposed to more credit risk than portfolios with a broader geographical 
diversification.

D. Use of estimates - The preparation of financial statements in conformity with
generally accepted accounting  principles requires management to make estimates
and  assumptions   that  may  affect  the  reported  amounts  in  the  financial
statements.



(2) LINES OF CREDIT
The Funds  participate with other USAA funds in two joint  short-term  revolving
loan  agreements  totaling  $850  million,  one with  USAA  Capital  Corporation
(CAPCO), an affiliate of the Manager ($750 million uncommitted), and one with 
NationsBank of Texas, N.A. ($100 million committed).  The purpose of the 
agreements is to meet temporary or emergency cash needs, including redemption 
requests that might otherwise require the  untimely  disposition of securities.
Subject to  availability  under its agreement with CAPCO,  each Fund may borrow 
from CAPCO an amount up to 5% of its total assets at CAPCO's borrowing rate with
no markup.  Subject to availability under its agreement with  NationsBank, each 
Fund may borrow from NationsBank an amount which,  when added to outstanding  
borrowings under the CAPCO agreement, does not exceed 15% of its total assets at
NationsBank's  borrowing rate plus a markup.  The Funds had no borrowings under 
either of these agreements during the year ended March 31, 1998.



(3) DISTRIBUTIONS
Net  investment  income  is  accrued  daily  as  dividends  and  distributed  to
shareholders monthly. Distributions of realized gains from security transactions
not  offset by  capital  losses  are made in the  succeeding  fiscal  year or as
otherwise required to avoid the payment of federal taxes.

The Funds completed  their fiscal year on March 31, 1998.  Federal law (Internal
Revenue Code of 1986, as amended, and the regulations  thereunder) requires each
Fund to notify its  shareholders  after the close of its taxable year as to what
portion  of  its  earnings  was  exempt  from  federal   taxation  and  dividend
distributions which represent long-term capital gains. The net investment income
earned and  distributed  by each of the Funds was 100% tax  exempt  for  federal
income tax purposes.  There were no long-term capital gain distributions for the
year ended March 31, 1998.



(4) INVESTMENT TRANSACTIONS
Cost of purchases and proceeds from  sales/maturities of securities for the year
ended March 31, 1998 were as follows:

                     USAA Texas Tax-Free USAA Texas Tax-Free
                         Income Fund     Money Market Fund

Purchases                 $16,934              $16,587
Sales/maturities          $ 8,533              $15,235

For the USAA Texas  Tax-Free  Income Fund,  cost of purchases  and proceeds from
sales/maturities excludes short-term securities.

Gross unrealized  appreciation and depreciation of investments at March 31, 1998
was as follows:
                        Appreciation        Depreciation       Net

(5) TRANSACTIONS WITH MANAGER
A. Management fees - The investment  policies of the Funds and the management of
the Funds' portfolios are carried out by USAA Investment Management Company (the
Manager).  Management fees are computed as a percentage of aggregate average net
assets (ANA) of both Funds  combined,  which on an annual basis is equal to .50%
of the first $50  million,  .40% of that  portion  over $50 million but not over
$100  million,  and .30% of that  portion  over  $100  million.  These  fees are
allocated on a proportional basis to each Fund monthly based upon ANA.

The Manager has voluntarily  agreed to limit the annual expenses of each Fund to
 .50% of its average net assets through August 1, 1999.

B. Transfer agent's fees - USAA Transfer Agency Company,  d/b/a USAA Shareholder
Account Services, an affiliate of the Manager,  provides transfer agent services
to the Funds  based on an  annual  charge of $26 per  shareholder  account  plus
out-of-pocket expenses.

C.  Underwriting  services - The Manager  provides  exclusive  underwriting  and
distribution  of the Funds'  shares on a  continuing  best  efforts  basis.  The
Manager receives no commissions or fees for this service.



(6)  TRANSACTIONS WITH AFFILIATES
Certain trustees and officers of the Funds are also directors,  officers, and/or
employees  of the  Manager.  None of the  affiliated  trustees or Fund  officers
received any compensation from the Funds.
